Flexible dataTaker Systems Let You Monitor Almost Any Value Turning Point Analysis is a method of data compression for arbitrary waveforms. The incoming waveform is sampled at speed and analyzed in real time to identify the turning points (Maxima and Minima) of the waveform, and the value and time of the turning point are also … Continued

Advanced New Data Loggers Increase Communications Options Recently the market has seen an increased interest in smaller models of battery-powered data loggers featuring wireless communications interfaces. These convenient systems rely on proprietary wireless protocols to provide the best mix of range and battery life, often lasting a full year or more. Data can be sent … Continued

Data Collection, Storage and Transmission Introduction Recent local, state and federal mandates such as RICE NESHAP require the reduction of harmful emissions (both particulate and NOx) from diesel engines used in off-road equipment, generators, buses and construction equipment. A variety of control technologies exists, but each is best suited for a specific engine use map, … Continued

Processors with Sub-Microsecond Response Times Control a Variety of I/O *Adapted from PID Control with ADwin, by Doug Rathburn, Keithley Instruments By Terry Nagy, Computer Aided Solutions, LLC. Introduction One of the most common automatic control methods is the Proportional-plus-Integral-and-Derivative (PID) controller. Industrial controllers utilizing this technique are used for controlling processes like those found … Continued

Ensure Accurate Readings with Galvanically-Isolated Devices 4-20 mA (milliamp) measurements are common in many industrial applications, including process monitoring and machine condition monitoring. However, to perform accurate measurements, users must take several precautions beforehand. In our latest White Paper, CAS DataLoggers covers the basics of 4-20mA current loop measurements in an industrial setting.   Examining … Continued
